XYZ Racing Tarmac Rally Coilovers — Infiniti G37 COUPE CONVERTIBLE USA (Modified Rear Integrated) 2009-2013

The G37 carries Infiniti’s naturally aspirated VQ37VHR V6 over the nose of a heavy FM-platform chassis shared with the 370Z, and on a rutted or crested tarmac stage that mass wants to keep travelling long after the front wheels have changed direction. Sealed-stage rally surfaces are rarely as smooth as a circuit kerb – mid-corner bumps, compressions and camber changes arrive without warning, and a road-biased damper will either crash through them or pack down and skip.

XYZ Racing’s Tarmac Rally coilover for the G37’s IN07-1 chassis code is built around that specific problem: absorbing a hard, unpredictable hit without unsettling the car for the next one. This is a stage-focused set-up rather than a fast-road compromise, and it is specified for both coupe and convertible variants of the 2009-2013 G37.

What this coilover brings to your build

Fitted to a 2009-2013 G37, the immediate change is how the car deals with the second and third hit in a sequence, not just the first. Where a stock or soft aftermarket damper lets body movement carry on after a big compression, this unit is tuned to suppress that follow-through shock, so the chassis settles rather than continuing to pitch into the next surface change. That control keeps more of the tyre’s contact patch loaded through the compression rather than letting it skip, which on a Tarmac Rally stage is the difference between the G37 staying pointed and the nose pushing wide. The heavier front end that comes with the VQ37VHR benefits in particular, since it’s the axle most likely to bottom out under braking into a rough entry.

About the Tarmac Rally coilover

XYZ Racing’s Tarmac Rally line is a damper built specifically around sealed-stage road surfaces rather than smooth circuit tarmac. The core job is absorbing the impact of an uneven road – the kind of broken camber, patched repairs and mid-corner lips that stage rally routes are full of – without transmitting that jolt straight into the chassis. Internally, the valving is set to suppress the body’s shock response after a big hit, keeping the tyre loaded and in contact with the road rather than letting the wheel unload and skate. XYZ describes the result as vehicle stability that lets the driver read the car’s handling accurately through a stage, and the settings on this kit come directly from XYZ’s own Tarmac Rally programme rather than a generic road-spring base tune.
